simonb 183066a619 Remove some assigned-to but otherwise unused variables. 2003-10-31 03:32:19 +00:00
thorpej 4011fcfefd Cache the "adjusted" value of sb_max when sb_max is changed, in order 
to avoid doing quad math in sbreserve().

Change suggested by Simon Burge, and code inspired by a similar change
in FreeBSD.

simonb 59fb31d7cc Remove unreachable break after return and goto statements. 2003-10-19 01:44:48 +00:00
christos 1f6ab188f9 If the user passes enough space, output the per cpu states instead of 
aggregating them.

kleink cad1622bfb Need opt_posix.h for P1003_1B_SEMAPHORE. 2003-10-02 09:30:16 +00:00
itojun d104a1a89a make debug_sysctl() sysctl MIB check more strict. from smak. 
attack similar to NetBSD-SA2003-014 can be mounted due to this flaw.

dsl eed203ed54 Simod has persuaded me to remove the 'sizeof (struct kinfo_drivers)' field. 2003-09-28 13:24:48 +00:00
dsl 84577b4fe4 Add kern.root_partition (sysinst needs to know it) 
Add kern.drivers - reports driver names and major numbers
Remove some redundant caddr_t casts.
 2003-09-27 07:58:55 +00:00
ragge 412d4e7d1b Use correct basic types when addresses are given in function calls. 2003-09-03 11:36:52 +00:00
atatat 2768d776d4 Use pfind() in proc_sysctl() to find the target process instead of a 
home-grown routine.  Remove defcorenamelen, since it's not used
anywhere.
 2003-08-24 19:20:40 +00:00
itojun e5255bfd47 make proc.curproc.* check more strict. atatat 2003-08-24 06:11:19 +00:00
itojun 95758d3554 avoid oldlenp mixup (in-kernel pointer and userland pointer). from atatat 2003-08-14 05:14:52 +00:00
agc aad01611e7 Move UCB-licensed code from 4-clause to 3-clause licence. 
Patches provided by Joel Baker in PR 22364, verified by myself.
 2003-08-07 16:26:28 +00:00
yamt b0cdf0a26d maintain the list of namecaches attached to the vnode. 
it makes vnodes freeable.
 2003-07-30 12:09:46 +00:00
ragge ef18f28fe4 Make somaxkva modifyable via sysctl (and compile-time) instead of 
hardcoding its size.
 2003-07-02 20:07:45 +00:00
fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage, 
and need to be examined and discussed more.
 2003-06-29 22:28:00 +00:00
enami e946a4baa0 Adjust !LKM case for proc * -> lwp * change. 2003-06-29 02:23:19 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can 
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 2003-06-28 14:20:43 +00:00
martin d505b18964 Make sure to include opt_foo.h if a defflag option FOO is used. 2003-06-23 11:00:59 +00:00
jdolecek 5fe02453b5 put back nmaxproc check mistakely changed in rev.1.132 
checking against nprocs is wrong in any case btw - we do allow
maxproc higher than number of current processes, it would just mean
no new process could be started until number of processes would
be lower than the new limit
 2003-03-27 18:34:18 +00:00
dsl 9be8ac5294 Alternative pid/proc allocater, removes all searches associated with pid 
lookup and allocation, and any dependency on NPROC or MAXUSERS.
NO_PID changed to -1 (and renamed NO_PGID) to remove artificial limit
on PID_MAX.
As discussed on tech-kern.
 2003-03-19 11:36:32 +00:00
thorpej 9e7bb2595e Based on the feedback on wasabisystems.com!bsd-api-discuss (sure wish 
people would read that list in a more timely fashion!), change the new
64-bit memory reporting sysctl nodes to report bytes.  This should not
be a problem, since it's only a week old, and no applications use the
new nodes yet.
 2003-03-06 20:32:59 +00:00
dsl 35df36296b Report correct values for p_uutime_{u}sec, p_ustime_{u}sec and p_uctime_{u}sec 2003-03-05 11:46:49 +00:00
enami e8083140e3 Cosmetic changes. 2003-03-01 23:48:44 +00:00
atatat 40f3045957 Add p_svuid and p_svgid to kinfo_proc2. Populate them in the kernel 
and in libkvm.  Then teach ps how to show them to you.

Also, teach ps how to show the names for all the uids, the rest of the
group numbers, and the "group access list".
 2003-03-01 05:41:55 +00:00
thorpej 922f0e9b78 Add hw.physpages and hw.userpages, which return the physmem and usermem 
values as a u_quad (page count).  Necessary for reporting memory on systems
with >=4G.  Per disussion on wasabisystems.com!bsd-api-discuss.
 2003-02-27 01:39:56 +00:00
dsl 9926e89884 Fix support for 16 character lognames 
(approved by christos)
 2003-02-15 18:47:41 +00:00
atatat a8481319cb Add a kern.dump_on_panic sysctl variable (and documentation, and a 
kernel config option) that controls whether the kernel dumps to the
dump device on panic.  Dumps can still be forced via the ``sync''
command from ddb.  Defaults to ``on''.
 2003-02-10 00:35:15 +00:00
kleink 71d7654509 Add sysconf(3) knobs for recent additions. 2003-02-02 20:33:05 +00:00
thorpej e0d8d366df Merge the nathanw_sa branch. 2003-01-18 10:06:22 +00:00
jdolecek 94062cc04a add support for optional arch-specific restriction of valid value 
for kern.maxproc
 2002-12-16 18:15:18 +00:00
jdolecek 300acddf8c don't allow kern.maxproc bigger than PID_MAX - PID_SKIP; the pid allocation 
code in fork1() would enter endless loop if all the allowed pids are taken
by running processes
 2002-12-12 20:54:58 +00:00
jdolecek 5fd22809a5 Add kern.forkfsleep sysctl - set/get time (in miliseconds) for which 
process would be forced to sleep in fork() if it hits either global
or user maxproc limit. Default is zero (no forced sleep).
Maximum is 20 seconds.
 2002-12-11 19:14:34 +00:00
scw 39a5a9dc76 Add two sysctls: kern.labelsector and kern.labeloffset. 
These are of use to userland code which previously depended on the
hard-coded values of LABELSECTOR and LABELOFFSET to figure out the
location of the disklabel for a particular platform.

With the introduction of umbrella ports such as evbarm, evbmips, etc,
the location of the disklabel may vary between kernels for the same
MACHINE. This sysctl will allow userland programs to remain independent
of the particular flavour of MACHINE in such cases.

scw 0f91ed3dfa Quell uninitialised variable warnings. 2002-11-24 11:37:54 +00:00
simonb 928196073c White-space nits. 2002-11-20 04:29:31 +00:00
manu 99bc517790 Added sysctl to change all IRIX kernel values reported by uname and systeminfo: 
OS name, hw name, kernel version, and so forth.
 2002-11-09 09:03:56 +00:00
manu 9a4dfe85fa Added two sysctl-able flags: proc.curproc.stopfork and proc.curproc.stopexec 
that can be used to block a process after fork(2) or exec(2) calls. The
new process is created in the SSTOP state and is never scheduled for running.

This feature is designed so that it is esay to attach the process using gdb
before it has done anything.

It works also with sproc, kthread_create, clone...

perry 6858187df6 /*CONTCOND*/ while (0)'ed macros 2002-11-02 07:20:42 +00:00
matt 48bbf5f234 Use the queue macros from <sys/queue.h> instead of referring to the queue 
members directly.  Use *_FOREACH whenever possible.
 2002-09-04 01:32:31 +00:00
augustss 731d1eccf2 Get rid of sysctl for setting BCM2033 firmware path. It doesn't work 
for ports that don't include files.usb, and it's also not done quite
the way it should.
 2002-08-26 13:09:39 +00:00
thorpej 4bec56201d Fix signed/unsigned comparison warnings from GCC 3.3. 2002-08-25 22:51:05 +00:00
augustss cdbff56c90 Add sysctl support for hw.dev.ubtbcmfw (so I can set the firmware 
path for my BCM2033).
 2002-08-24 17:27:01 +00:00
itojun 0a9d2ad2d7 provide KERN_URND, which extracts sizeof(int) random number from the kernel 
(similar to /dev/urandom, for use within chroot jail).
 2002-07-02 17:06:17 +00:00
matt 0dc8ee943d Eliminate more commons or redundant declarations. 2002-05-14 02:58:32 +00:00
matt 44b3464a48 debug0, debug1, debug15 are defined elsewhere. XXX there needs to a 
better was of doing this.
 2002-05-13 07:13:58 +00:00
simonb 8bcefa5e82 Fix a typo that stopped this compiling in the !LKM case. 
Remove the buf2 variable from sysctl_sysvipc(), which was only ever
 assigned to but not used.
 2002-04-03 08:06:17 +00:00
jdolecek 3ffbb4470d make emul_sysctl() work with emulations loaded via LKM, properly bound check 
name[0]
